Answer:
0.19
Step-by-step explanation:
You do 2.85 divided by 15, and you do it with most of this type of equation. But get rid of the dollar sign and keep the dot
System of equation
(d + q = 15)0.10
0.10d + 0.25q = 2.85
0.10d + 0.10q = 1.50
Subtract both equation
0.15q = 1.35, q = 9
15 - 9 = 6
Solution: 9 quarters and 6 dimes
(d + q = 15)0.10
0.10d + 0.25q = 2.85
0.10d + 0.10q = 1.50
Subtract both equation
0.15q = 1.35, q = 9
15 - 9 = 6
Solution: 9 quarters and 6 dimes
